Caravaggio fled Rome to Naples in 1606. He was wanted for the killing of a rogue playboy, Ranuccio Tomassoni in a duel. Brilliant artist, crazy and out-of-control, you need to see his works that remain in the city. The Seven Acts of Mercy, a life-sized, dark and chaotic painting, hangs in the Pio Monte della Misericordia. The famous Flagellation, offers a shaft of light which illuminates Christ’s lifelike form, while he is tormented by a pair of shifty looking characters. See it hanging in the Capodimonte museum.
